It is necessary to imagine the sum of the areas between each z-score and the average.
Given as the ratio of the area under the normal curve between two z-scores, both above average.
The Z score accurately measures the number of standard deviations above or below the mean of the data points.
The formula for calculating the z-score is
z = (data points – mean) / (standard deviation).
It is also expressed as z = (x-μ) / σ.
- A positive z-score indicates that the data points are above average.
- A negative z-score indicates that the data points are below average.
- A z-score close to 0 means that the data points are close to average.
- The normal curve is symmetric with respect to the mean and needs to be investigated.
Therefore, to find the percentage of the area under the normal curve between two z-scores, both above the mean, you need to look at the sum of the areas between the z-score and the mean.

It has 90 degrees so it's right
And none of the sides are equal so it's scalene
The three consecutive integers are 127, 128, 129
<em><u>Answer:</u></em>
The answer is 70 degrees.
<em><u>Step-by-step explanation:</u></em>
1. All the angles in a circle add up to 360, and the red square thing in the TVU angle means it's a 90 degree angle.
2. Add 150 plus 50 plus 90 = 290
3. 360 degrees (total) - 290 degrees = 70 degrees! :)
